Visual Mathematics Challenge: Finding Shared Properties Among Mathematical Figures

Question

What do the four figures below have in common?

00:00 What is common to all illustrations?

00:02 Perpendicular lines create a right angle at their intersection point

00:05 In this example, the lines form a right angle therefore are perpendicular

00:08 In this one too

00:15 In this one too

00:19 And in this one too

00:22 All lines are perpendicular to each other and that's the answer to the question

Upon observation we can see that all the lines intersect forming a right angle of 90 degrees.

Typically intersecting lines that form a right angle of 90 degrees are perpendicular and vertical lines.

Therefore, the correct answer is a.

All the figures are perpendicular
